Cook like an egg in a Korean kiln
Consider yourself a sauna connoisseur? A Korean han-jeung-mak might test your limits. In between steam rooms and a punishing round of exfoliation, break a sweat in the ‘kiln sauna’ – alarmingly similar to an oven in appearance, this intensely heated dome uses burning wood and charcoal to heat the room, the style of which has barely changed style in 500 years. Eggs are a popular in-spa snack in Korea; you might spot a bowl of them inside the kiln, slow-cooking (just like you). Public bathhouses (jjimjilbang) around Korea have kiln rooms; try Dragonhillspa in Seoul.
Enjoy a snail’s pace across your face in Japan
How far would you go to get bright, clear skin? Centuries ago, geisha used uguisu no fun (nightingale droppings) to remove makeup and polish their skin. Nightingale faeces still makes its way into some beauty treatments and products, but the new vogue in Japan is for snails slithering across the skin.
